Specification of Letters Patent.

I Patented Oct. 26, 1909.

To all whom it may concern:-

Be it known that I, HARVEY-J. ZELL, a

citizen of the United States, residing at Dayton, 1n the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Paper Lunch-Boxes; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to-which it appertains to make and usethe same, reference being had to the accompanyand to the figures ofreference specification.

This invention relates to new and useful improvements in collapsiblepaper boxes,

especially adapted for lunches.

The object of the invention is to provide ,a paper lunch box which isfoldable to lie flat and to thus occupy but little space in shipment. Inother words, the boxes are folded before shipment, and in such foldedcondition are laid flat one upon the other to occupy a minimum space inshipment. When in the hands of the seller or user, the boxes are readilyopened out from their shipping position and ready for the contents tobev laced therein. I

In t e accompanying drawings, Fi re 1, is a plan view of the blank fromWhlCll the box is formed. Fig. 2, is a view of the box after beingformed from the blank and in a flattened or collapsed condition forshipment. Fig. 3, is a perspective view of the box opened from thecollapsedcondition shown in Fig. 2. Fig. 4, is a front elevation of thebox showing the same partially folded.

The completed box as shown in Fig. 3 is formed from the blank shown in.Fig. 1, and consists of a bottom 1,-front and rear sides 3and 3separated from the bottom by intervening parallel score lines. The ends2 2 are separated from the bottom by intervening scorelines, and thesaid ends 2 2 lie on the inner sides of triangular folds consisting ofend extensions 4, 5, 6 and 7 which are separated from the front and rearsides 3 and 3 by intervening score lines, and fold upon diagonal scorelines. The front and fastening devices 15, see Fig. 3. When the endwalls of the box consistlng of the folds 4, 5, 6 and 7 and the ends 2,are foldedflat as in Fig.2, the said ends fold inwardly upon the scorelines which separate the ends2 2 from the-bottom 1, and lie flat bybreaking upon the diagonal score lines 18 and 18'. The cover 9 isseparated from the rear side 3' by a score line, and said coverisalsoprovided with dia onal score lines 16 16 which intersect wit the scorelines 18 of the rear side 3. The score lines 16 of said cover areutilized when folding the boxfor shipment as in F ig. 2 in whichcondition, the portions 10 10 he against the portions 8'. The diagonalscore lines .16 extend beyond the score lines 17 which separate the ends11 11 of the cover, and by so extending said score lines 16 16, thecover 9 is permitted to lie flat as in Fig. 2; The ends l1 11 of thecover bend upon the score lines- 17 and lie on the inner sides of theends of the box when the cover is closed down upon the box. Theextension 12 also folds downwardly on the score line intervenin it and-the cover 9, and 'lies on the inner si e of the front wall 3 of the boxwhen said cover is closed. Y

It will be understood that the score lines 18, 18 and 16 are utilizedonly to collapse the box for shipment as in Fig. 2. When the box isfolded as in Fi 3, the score lines referred to are IlOt'lltlllZGCl, andthe folded box is prevented from breaking on such score lines by thecover being inserted in the mouth of the vessel, that isthe tonguesll 11and 12 engaging the inner sides of the ends and front of the box.

A flexible handle 14 is united to the ends of the box and serves tocarry the box by. .When the box is in the collapsed form shown in Fig.2, the flexible handle 14 yields readily to the folded position of thebox.

When it is desired to collapse the box, the various portions are movedas indicated by the arrows in Fig. 3; The front and'rear upon the otherand both upon the-rear side 3' with the 'cover 9 lying fiat upon saidfolded portions 8 and 10, andlikewise the folds Slie flat against thefront side 3 of thebox with the ends consistin of the portions 2 2'andthe triangular lds 4, 5,- 6

the portions 8 and 8'.

folded and united to the end walls 2 by the I sides flatten outwardly ina plane with the bottom 1; the portions 8 and 10 he one and 7 lyinginwardly against the bottom of the box.

Having described my invention, I claim: I 1. A collapsible box havin abottom and front and rear sides, said font and rear sides havingdiagonal score lines which permit the ends of the box to lie flatagainst the bottom of said box, and a cover joinin the rear side of thebox and having dlagona score lines which permitsaid cover to lie againstthe ends and rear side of the box when the box is collapsed.

2. A paper box comprisihg a bottom and front and rear sides, the bottomhaving end extensions and the front and rear sides havm onal score linesagainst the end extensions of the box; the front and rear sides of thebox having diagonal score lines, and cover joining the rear side of thebox pro end extensions which fold upon diagvided with diagonal scorelines which intersect with the dlagonal score lines on the rear side ofthe box.

3. A paper box comprising a bottom and front and rear sldes with endextensions forming the end closures of the box, a cover joining the rearside of the box and having marginal folds which lie on the inside of theends and front side of the box when said cover is made to close the box,the front side, rear side and cover of said box having diagonal scorelines which'enable said box to be folded in a flat condition forshipment.

In testiinon whereof I affix my signature,
